Well it means that the processor will continue executing the code of the jump address.

it jumps the give number of bytes from the JMP-opcode address.
that means startaddress+amount of bytes to jmp = endaddress (called a relative jmp) Smile

Please, don't think you JMP by hard addresses Razz

Oh yeah you're right Smile

using 0xEA (far jmp) instead of 0xE9 (relative jmp) is for an absolute jump Smile

it takes an address as argument Razz

that's nice and save the calculation to your jump Smile

Also it's worth noting that whatever debugger your using will figure out whether you need near or far jump automatically if you just put in jmp addr. So you need to be aware that the size of your far jump is likely a lot greater then the near jmp you might want to overwrite.
